Another object of the invention isto provide a device of the stated character which may be readily transported fromone candy. distributing machine to another. p Another object of the invention is to provide a device of the stated character wherein the polishing elements may be rotated at various speeds as desired.

Another object of he invention is topro vide a device of the stated character wherein the polishing elements may be readily removed or replaced for cleaning or otherpurposes.

Heretoforethe coating onthe'- candies has been polished manuallynduring the travel thereof on theconveyors. Such a practice takes a considerable amount of time, labor, and furthermore, is substantiallyineffective to produce the desired luster. By"

my invention, I provide a machine which a may be disposed above and transversely of the conveyors carrying the candies andwhich .maybe adjusted vertically'with respect to the candies passing 'therebelow, effectively polishing the said-candies in considerably faster time and reducing the amount of labor required.

A particular feature of my invention re;

sides inthe manner inwhich I dispose the polishing elements, the operating functions and features of which will bG'dlSOHSSBd at length hereinafter, I Referring to the drawings, a, machin e each having'a horizontal base portion 2, and

outwardly extending lugs 3 and. 4 respectively, the purpose for'which will be set forth 15 made in accordance with my invention com? prlsesa pair of spaced upright supports 1, 1

hereinafter. The supports 1, 1 are each furrespect thereto, by as bolts 8.-

A cro s headgihaling the cent-m1 pot; so 7 from. the ends ofthe said cross head' and .55 formed in the uprightsupportslat which point the said extensions 10 are threaded on aha-11d screw 11 rotatably secured in the -out'wardextensions 3 and 4 of the uprights 1-, 1 respectively. The removal of the hand screw "11 fromthe supports is'prevented by the adjustable collars 12, upperfaces of raised or lowered as the operator of the machine desires.

A plurality of shafts 14 are vertically and rotatably mounted in the cross head 9 as shown in Fig. 4, of the drawings, the said shafts extending a suitable distance below the cross head. The polishing elements which, in the present instance are ordinary stock brushes consisting of goat hair bristles 15 secured in a wooden handleor base 16,

are mounted in clips 17 which are secured at V the lower ends of the shafts 14. The clips 17 in the present instance have a plurality of depending fingers 18 adapted to effective ly grip the under surface of the brush base 16 and are further provided with a spring strip 19. by means of which sufficient pres sure is applied to the top of the brush base 16 to normally prevent the removal of the brush resting on the depending fingers 18' from the holder and yet, will permit the easy removal thereof when it is desired to cleanse or replace the worn brushes. The brush clips 17 are secured to the lower eXtermity of the shafts 14 by means of a collar 20 centrally located on the upper surface of the brush clip 17, the said collar 20 being secured on the shaft 14 by the set screw 21.

A gear 22 is rigidly mounted on each of the shafts 14: in the cut-out portion of the cross head 9, the teeth 23 of each of the said gears 22 being in. interlocking engagement with the teeth of the gear wheels disposed adjacent thereto. To effectively rotate the polishing elements, I extend one of the shafts 14 a suitable distanceabove the upper surface of the cross head 9 and secure a parallel friction plate 24 at the upper extremity thereof by means of a set screw 25. Con- I nection between the friction plate 24: and a motor 26 is accomplished by means of a friction element 27 rigidly mounted on the shaft 28 of the motor 26, the said friction element contacting with the upper face of the friction plate 24 and effectively imparting rotation thereto which rotation is transmitted by means of the gear elements 22 to each of the polishing elements.

As stated above the particular feature of my invention resides in the novel arrange ment of the clips adapted to receive the polishing brushes, the said clips being positioned in such a manner that the paths, described by the rotation thereof, intersect and at the same time no contact between adj acent- 1y disposed elements being possible, and it should be pointed out that such an arrangei tioning the polishing elements, every piece of candy passing thereunder on the coated sheets of paper carried by the conveyors is acted upon by at least one of the said elements, a substantial number of times, regardless of the position of the candy on the conveyor. During the passage of the candy beneath the polishing elements, every contact of the polishing elements with a piece of the candy is at a different angle from the previous contact, thus producing a polish that is uniform, highly effective, and gives a greater luster to the product.

Also by my invention 1 am able to utilize polishing element which are stock articles on the open market and effecting considerableeconomy.

While I have described a particular embodiment of my invention for the purpose of description it will be apparent that certain modifications and changes in the detailed construction thereof may bev incorporated without departing from the spirit of the invention. I
